JACOB L OUIS BAUER. AND ROBERT BATTER, OF MILWAUKEE, WISCONSIN.

FOOD-COMMINU'IING- DEVICE.

Application filed. March 25, 1919.

To all whom it may concern:

Be it known that we, JACOB L. BAUER and ROBERT BAUER, citizens of the United States, and'residents of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Food-Connninuting Devices; and we do hereby declare the'following is a full,

' clear, and exact description thereof.

Our invention relates to new and useful improvements 1n machlnes for shredding or comminuting food materialSQand more parsmall type adapted for handle member is transformed into reciprocating motion of a cutting or shredding member, and whereby free discharge of material from the cutting or shredding member is permitted.

A further object resides in the provision of improved and simplified manually operative means for feeding the work material to the cutting or shredding member of the device A still further object resides in the provision of an arrangement, in a structure compassing the foregoing objects, wherein cutting or shredding members of different types may be readily substituted, to adapt the machine for difierent desired operations.

With the above and other objects and advantages in view, which will'be apparent as the description proceeds, our invention resides in the novel features of construction, combination and arrangement of parts, as hereinafter more particularly described and defined by the appended claims;

In the accompanying drawings:

Figure 1 is a vertical sectional view through a food comminuting machine embodying our invention, the plan of this sec tion being indicated in general by the line Fig. 2 is a plan view of the machine, portions being broken away to more clearly show the structure.

Specification of Letters Patent.

Patented Dec. 16, 1919. Serial No. 284.945.

Fig. 3 is a rear view of the upper portion of the machine.

Fig. 4.- is an elevational view of a shredding member adapted for use in the machine. I

Referring now more particularly to the drawings, the embodiment of our invention therein shown is adapted to be mounted in the usual manner on the edge of a table or other support, and to this end includes a standard 5 having its upper portion offset whereby to lie inwardly of the edge of the support, the lower portion of the standard carrying a support engaging jaw 6 and having its lower extremity'laterally directed for the reception of a clamp screw 7 whereby the standard maybe firmly clamped to the table or other support. The upper end of the standard carries cross arms 8 having bars 9 projecting horizontally from their outer ends and adapted to pass through the outstanding lugs 10 at the inner end of a feed cylinder 11' for the material to be worked upon. The free end portions of the bars are shouldered to afford seats for the cylinder lugs, and wing nuts 12 are threaded "on the bearings to clamp the lugs against the shoulders whereby the cylinder may be firmly and rigidly mounted in a manner which is, however, quickly detachable. The ends of the feed cylinder are entirely open, and a vertical wall 13 is carried by the inner end of the cylinder. Secured to this guide wall at the sides of the cylinder opening are a pair of track ways each formed of a strip of metal 14 bent longitudinally to aiford a channel shape therefor and having one side secured to the wall by rivets 15 passed there- 'through and through a spacer strip'16 disposed in the channel.

The members for cutting, shredding or otherwise comminuting the work material are each in the form of a fiat plate 17 having its edge portions engageable in the channels of the trackways whereby it is mounted for vertical reciprocating movement, and the cutting portions .of the comminutingmembers are struck inwardly from the body of the plate, thus forming apertures in the plate through which the comminuted mate rial passes. The cutting portions of the 'oomminuting member may comprise shredding blades 18 extending transversely throughout the major portion of the width of the plate in apreferablyoblique direction, and as shown in Fig.4, wherei'nthe" comminuting member is designated 17 the cutting portions may comprise a multiplicity of grater tongues 19.

For reciprocating the comminuting member, a transverse plate 20 is mounted on the back of the member, in spaced relation there to, by rivets 21, spacing sleeves 22 being disposed on the rivets between the comminuting plate and said transverse plate. This transverse plate is provided with a longitudinal slot 23 forming a track way in which is engaged a roller 2% mounted on pin 25 carried on the end of a crank arm 26 which extends from a shaft 27 ournaled in a bearing boss on the upper end standard 5, this crank being rotated between the support bars 9 of the feed cylinder. Outwardly of the boss 28, the shaft 27 is squared for the reception of a crank handle 29, which is retained in place by a wing nut threaded on the end of the shaft.

Thus rotary motion of the crank handle 29 will be transformed in the vertical reciprocating motion of the comminuting member, to effect its operation, it being noted that the operative stroke of the comminuting member is preferably effected on the down stroke of the crank handle, to procure the most easy operation.

The upper portion of the feed cylinder 11 is apertured and enlar ed to provide a supply hopper 31, and to feed the material in the cylinder toward the comminuting member, a follower 32 is slidable therein, said follower carrying a handle 33 which projects from the. outer end of the cylinder. Movement of the follower from the outer end of the cylinder is normally prevented by stop lugs 34, and to permit this detaching movement for the purpose of cleaning the device, the follow member is provided with peripheral slots 35 adapted to register with and receive the stop lugs.

In the operation of our device, food material to be worked'up'on is placed in the cylinder 11. through the hopper 31 thereof, the operator then grasps the crank handle 29 and the handle 33 of the follower and rotates the crank handle, simultaneously pressing the followerinwardly to feed the work material to the reciprocating comminuting member. The comminuted material passes through the plate 17 and may be collected in any suitable receptacle disposed under the inner end portion of the cylinder. When it is desired to clean the machine after operation, or to substitute a different type of comminuting member, it is merely necessary to unscrew the wing nuts 12 and withdraw the feed cylinder, the comminuting member being then readily movable from its trackways and the entire device being thus completely exposed to permit a convenient and thorough cleaning thereof, it being noted particularly that the various parts of the device are so arranged as to avoid recesses or remote portions which would be diflicult of cleaning.

, While we have shown and described a preferred embodiment of our invention, it will be appreciated that various changes and modifications of structure to meet difiering conditions of use or manufacture may be employed without departing in any manner from the spirit of our invention, and that various phases of our invention may be em-.

ployed independently of the complete structure described, within the scope of the appended claims.

lVhat is claimed is: V
